$6/month. It's $3 for the first month (or first months, on longer subscription cycles, but it's first unit of subscription cycle at half price only).
At $6/month it's still pretty reasonable, IMO, and chucking less than $10 at it for three months probably gets you to the next pop-up token retailer offering introductory pricing, so long as the bubble doesn't burst before then.
I wound up subbing for the three months. My experience has been pretty positive, using Cline in VS Code and moving away from Qwen3 Coder on OpenRouter. Q3C did a good job overall but I was using the free model (with $10 credit sitting on OR to increase limits) and that's pretty painful to sit through repeated 429 errors. GLM-4.6 has been comparable, maybe a fraction worse, but without 429 errors it blazes through tasks.
